in reply to Getting Locations using Distance
The easiest approach is to traverse your list of locations and compute the distaance of each location from your designated position. To get locations of zip codes, try
Geo::Coder::US:
To compute distances, use Geo::Ellipsoid:use Geo::Coder::US; Geo::Coder::US->set_db( "geocoder.db" ); my ($ora) = Geo::Coder::US->geocode( "1005 Gravenstein Hwy N, 95472" ); print "O'Reilly is located at $ora->{lat} degrees north, " "$ora->{long} degrees east.\n";
use Geo::Ellipsoid; $geo = Geo::Ellipsoid->new(ellipsoid=>'NAD27', units=>'degrees'); @origin = ( 37.619002, -122.374843 ); # SFO @dest = ( 33.942536, -118.408074 ); # LAX ( $range, $bearing ) = $geo->to( @origin, @dest ); ($lat,$lon) = $geo->at( @origin, 45.0, 2000 ); ( $x, $y ) = $geo->displacement( @origin, $lat, $lon ); @pos = $geo->location( $lat, $lon, $x, $y );
